Answer 1
Answer:

Answer:

1) $101,400

2) $27,000

Step-by-step explanation:

1) For this, we can first find how much she makes in a year from her salary alone:

$2,200×12= $26400.

Now, she also received a commission of 2.5%, so we can take this percentage from 3 million to find the total from commission:

3,000,000×0.025= $75,000

Adding these two gives us a total of $101400.

2) We can use the Simple Interest Formula to solve this (I= Prt). Plug in the values given to give us:

I= 5000(1.08)(5)

I= $27000

A high school student volunteers to present a report to the administration about the types of lunches students prefer. He surveys members of his class and records their choices. What type of sampling did the student use? systematic random sampling voluntary sampling convenience sampling stratified sampling

Answers

The student use convenience sampling.

This is convenience sampling because in this type of sampling we use closer part of the population. Here the person is surveying his classmates, the closest samples available. In this type of sampling, it is easy to gather samples because every members are of their class easily available to give the survey.

Hence this type of sampling called convenience sampling.

9) Which equation represents the line that passes through the point (3,4) and is parallel to the x-axis?A x = 4
B x = 3
C y = 4
D y = 3

Answers

Since the line is parallell to the x-axis we know the slope is zero: m=0

Using the point-slope formula we can substitute know values:
y=mx+b
4=0(3)+b
b=4
y=0x+4
y=4

You could also jsut do it by inspection: since it passes through (3,4) and is horizontal it must cross at (0,4) i.e. all y=4.

Final answer:

The equation of the line parallel to the x-axis and passing through point (3,4) is 'y = 4'. Thus, the correct answer is C y=4.

Explanation:

The question asks for the equation of a line that is parallel to the x-axis and passes through the point (3,4). In the Cartesian coordinate system, a line parallel to the x-axis will have a constant y-value and an equation in the form of y = k, where k is the constant y-value. In this case, the y-coordinate of the given point is 4, which is our constant. Thus, the line parallel to the x-axis passing through the point (3,4) is y = 4. So, the correct answer is C y = 4.

The probability for success of an event is P(A), and the probability of success of a second event is P(B). What is the probability of both events occurring, in that order?A. P(A + B)
B. P(A) • P(B)
C. P(A) + P(B)
D. P(A x B)

Answers

Answer:  The correct option is (B) P(A) • P(B).

Step-by-step explanation:  Given that the probability for success of an event is P(A) and the probability of success of a second event is P(B).

We are to find the probability of both events occurring, in that order.

We know that

if two events are independent of each other, then the probability of the intersection of the two events is given by the product of the probabilities of the events.

Here, the event that both events occur is given by (A ∩ B).

And, so the probability of both events occurring, in that order will be

P(A\cap B)=P(A).P(B).

Thus, the required probability is P(A) • P(B).

Option (B) is CORRECT.

D. P(A x B)

To work out the success of both events you have to multiply them together. I'd seriously reccomend learning this rule as it's very important later on in mathematics as it's basically the foundation of all probability statistics.
